The requirements for documents needed at check-in depend on the type of accommodation and the applicable regulations. For hotels and other accommodation facilities, a Russian passport, an international passport, or a driver’s license may be accepted. For apartments, serviced apartments, and other properties where check-in or contract conclusion is carried out according to the rules of a specific property, the required documents are determined by the property itself. Remote round-the-clock check-in is organized. For check-in instructions, guests must contact the property during business hours: from 9:00 AM to 10:00 PM.
